Application filed April 16, 1915. Serial No. 21,817.

To all whom it may concern Be it known that I, HENRY O. QUESEN- BERRY, a citizen of the United States, residing at Delton, in the county of Pulaski and State of Virginia, have invented a new and useful Rail-Gripping Attachment for Jacks, of which the following is a specification.

his invention relates to a rail gripping attachment for lifting jacks.

hen it is desired to raise a rail secured to ties on a bridge structure, it has heretofore been necessary to use a pinch bar for this purpose, such use involving considerable time and labor.

One of the objects of the present invention is to provide a novel form of rail griprail, will permit the use of an ordinary lifting jack which, when placed on a tie, can be used to elevate the rail from t e tie.

A further object is to provide a gripping which is simple and durable in construction and can be easily plalced in and removed from position on a rai lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in .the com within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown. In said drawings :Figure 1 is an end elevation of the device in position on a rail, a jack being indicated by dotted lines. Fig. 2 is a plan view of the structure shown in Fig. 1. Fig. 3 is a gripping device. eferring to reference 1 perspective view of the a head 3 which is undercut as at 4 sofas to recelve one of the base flanges of the rail R.

Extending from the mid In using the device herein described, the arms 2 are placed under the rail R at opposite sides of the tie and are then raised and shifted so flange of the rail R in engagement with the heads 3. Yoke 1 is then swung upwardly toward the rail so as to bring the stud 5 against the outer side of the head of the rail While the parts are thus positioned a jack indicated generally at J, is inserted between the tie T and the arm 6 and by operating the jack it will be apparent that the arm 6 and yoke 1 will be pushed upwardly, thus lifting the rail off of the tie T. During this lifting operation, the stud 5 will press tightly against the side of the head of the rail, while the heads 3 will pull tightly against the inner base flange of the rail.

y means of a device such as described, it is possible to mount the entire lifting mechanism upon a single tie, the yoke 1 straddling the tie, while the jack J rests upon said tie. Thus the device is especially useful upon bridges and like structures.

The depending. lug 7 constitutes means for preventing the jack from slipping laterally from under the arm 6.

at is claimed is 1.. A rail gripping attachment for lifting jacks, including a yoke adapted to straddle a tie, arms extending from one side of the yoke for extending under a rail, means on the arms forengaging the base flange at one side of the rail, means on the yoke for en gaging the head of the rail at the other side thereof, and a jack engaging arm extending from'the yoke.

2. A rail gripping attachment for lifting jacks, including a yoke adapted to straddle a tie, arms extending therefrom and adapted to project under a rail at the tie, rail engaging heads upon the arms Patented Aug. 3, 1915.

opposite sides of I for engaging the base flange at one side of rny own, I have hereto afliXed my signature the rail, means on the yoke forengaging in the presence of two Witnesses.

the head of the rail at the other side thereof, 7 an arm extending from the yoke at that side, I QUESENBEBRY' 5 remote from the rail engaging means, and. a Witnesses:

jack retaining 111g upon the arm. 7 J., M. NUNN, I
